Patented Jan. 2, 1934 stares PATENT QFFEQE 8 Claims.

This invention relates to improvements in hinges and refers more particularly to hinges all parts of which are hidden from View when the door on which they are mounted is closed, and

which are frequently referred to as concealed hinges.

It is an object of the invention to provide a concealed hinge wherein an outwardly projecting arm integral with one hinge member furnishes guidance for the movement of the other hinge member by engaging pivotally mounted quadrants in the latter; moreover by adjustment of the quadrants the throw of the hinge members when angularly inclined to one another may be varied.

Another object of the invention is to provide such a hinge wherein the outwardly projecting arm is also pivotally connected to links which are also pivotally mounted at their otherextremity 20 on the hinge member which swings relative to the member from which the said arm projects.

A further object of the invention is to provide a concealed hinge which is relatively cheap and simple to manufacture, and wherein provision is made for ready adjustment of the throw of the two members when angularly inclined.

With these and other objects and advantages in view which will become apparent as the specification proceeds, an embodiment of the invention is hereinafter more fully described with the aid of the accompanying drawings, in which:

Figure 1 illustrates a side elevation of my hinge with the two hinge members mounted on a door and doorframe respectively and the door in closed position.

Figure 2 shows a side elevation of one hinge member, and

Figure 3 is a plan view of Figure 2.

Figure 4 shows a side elevation of the other hinge member, and

Figure 5 is a plan view thereof.

Figure 6 is a diagrammatic view showing a plurality of hinges supporting a door in open position from a curved door frame.

Figure '7 is a section on the line 77 of Figure 8, and

Figure 8 is a section on the line 8-8 of Figure '7.

Figure 9 is a section on the line 99 of Figure 10, and

Figure 10 is a section on the line 1010 of Figure 9.

Figure 11 is a View showing the front of a hinge member mounted on a door and disposed at substantially 90 degrees to the other member supported by a door frame; in this case the throw of the angularly disposed members is very slight.

Figure 12 is a view similar to that shown in Figure 11 except that the hinge is so adjusted as to afford a considerably greater throw.

The hinge consists of two members 1 and 2. The member 1 is usually mounted on a doorframe 3 as by screws i, and the member 2 is attached to a door 5 as by screws 6.

Integral with the member 1 is an outwardly projecting curved arm 7 which, in the present instance, has two aligned horizontal slots 8 therethrough which extend for a portion of its length. Into each slot 8 one extremity of a curved link 9 extends, and both links are pivotally supported by a common pin 10 which passes through them and also through the said arm 7. In the member 2 adjacent its front inner corner 2a two vertically aligned recesses 11 are formed to receive the opposite extremities of the links 9 which are pivotally supported by a common pin 12 which also passes through the member 2.

Thus the curved arm '7 and links 9 provide a support for the member 2 relative to the memoer 1 whereby pivotal movement of the former relative to the latter is permitted, and further the front inner corner 2a of themember 2 may assume positions at varying distances in front of the member 1. In order that this distance may be controlled and adjusted to suit varying conditions slotted segments 14 are employed, in the present instance both above and below the arm '7. These segments are each pivotally mounted adjacent one of their extremities about a common axis by pins 15 which extend through the upper and lower sides of the member 2 adjacent its rear inner corner. Extending through the outer extremity of the arm 7 is a pin 16 which also extends through the slots 14a in the segments 14 and is slidable in the latter. Thus by moving the segments about their axes the throw of the member 2, that is its distance in front of the member 1 when angularly inclined to the latter,

' may be regulated.

In order to hold the segments 14 against acci dental movement curved v slots 17 are formed through the upper and lower sides of the member 2 and 18 denotes screws which extend through these slots and are in threaded engagement with tapped holes 19 provided in the segments 14.

From Figures 9 and 12 it will be noted that when the segments 14 are moved towards the inner side of the member 2 to increase the throw of the latter their free extremities extend forwardly beyond the front face of the member 2. For that 1 reason recesses 20 are formed in the face of the member 1 to receive the said segments so that the adjacent faces of the members 1 and 2 may lie contiguous to one another when the hinge is in closed position irrespective of the throw for which the hinge is set.

From the foregoing it is believed that the operation of the hinge will be readily understood. Briefly it is as follows: Before inserting the hinge member 2 into a door the screws 18 should be loosened and the segments turned about the pins 15 until the desired throw of the member 2 is obtained. Then the screws 18 are tightened and the member 2 secured in place the door 5.

As previously stated the curved links 9 support the member 2 relative to the arm 7, and the position of the segments 14 governs the outward swing of the member 2 since it is movable transversely of the latter.

While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that the construction is susceptible to such alterations and modifications as fall within the scope of the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. A hinge comprising two members, an outwardly projecting arm integral with one of said members, guide means pivoted on the other member, cooperating means in said arm and guide means along which said arm is adapted to travel, means cooperating with said other member for holding said guide means against pivotal movement, and supporting means for said other member pivoted thereto and to said arm.

2. A hinge comprising two members, an outwardly projecting arm integral with one of said members, slotted guide means pivoted on the other member, a pin extending from said arm engaging said slotted guide means and adapted to travel in the latter, means normally holding said slotted guide means against pivotal movement, and supporting means for the other member extending from said arm.

3. A hinge comprising two members, an outwardly projecting arm integral with one of the members, the other member having a recess formed therein to receive said arm when the hinge members are in closed position, guide means pivoted on said other member, means normally holding said guide means against pivotal movement, cooperating means in said arm and guide permitting the former to travel along the latter, and supporting means for said other member so connected to said arm that as the guide means move pivotally the throw of the hinge members varies.

4. A hinge comprising two members, an outwardly projecting arm integral with one of the members, the other member having a recess formed therein to receive said arm when the hinge members are in closed position, slotted guide means pivoted on said other member, means normally holding the guide means against pivotal movement, a pin extending from the outer extremity of said arm adapted to travel in said slotted guide means, and supporting means for said other member so connected thereto and to said arm that as the guide means move pivotally the throw of the hinge members is varied.

5. A hinge comprising two members, an outwardly projecting arm integral with one of the members, said arm being longitudinally slotted, supporting means for the other member pivoted thereto and to said arm, said supporting means extending into the slotted arm, slotted guide means pivoted on the other member, a pin extending through said arm and said slotted guide means so that said arm may move along said guide means, and means normally holding the latter against pivotal movement.

6. A hinge comprising two members, an outwardly projecting arm integral with one member, segmental guide means segmentally slotted and pivoted on said other member, means extending from said arm adapted to travel in said slotted segmental guide means, means preventing pivotal movement of said guide means, and

supporting means for said other member extending-from said arm.

'7. A hinge comprising two members, an outwardly projecting arm integral with one member, said arm being longitudinally slotted, supporting means for the other member pivotally connected thereto and to said arm, said supporting means extending into said slotted arm, segmental slotted guide means segmentally slotted and pivoted on said other member, a pin projecting from said arm adapted to travel in the slotted guide means, and means normally preventing movement of said guide means.

8. A hinge comprising two members, an outwardly projecting arm integral with one member, longitudinally slotted guide means pivoted on the other member, a pin extending from said arm adapted to travel in the slotted guide means, said other member being segmentally slotted, fastening means extending through said slotted' member and cooperating with said guide means to prevent accidental movement of the latter by frictionally engaging said other member, and supporting means for said other member connecting thereto and to said arm.
